    Period T = 0.1 second

    Explanation:

    Given that the

    wavelength = 500 meters

    speed V = 5000 meters per second

    The wave speed is the ratio of wavelength to period of the wave. That is,

    V = λ/T

    Where

    V = wave speed (m/s)

    λ = wavelength (m).

    T = period (s)

    Using the formula above gives

    5000 = 500/T

    Make T the subject of formula

    T = 500/5000

    T = 0.1 s
